This study introduces a computer-assisted haptic simulator for training colonoscopy procedures. The system combines virtual reality software with a haptic hardware interface for realistic surgical skill development.

Area of Science:

  • Medical Simulation
  • Surgical Training
  • Gastroenterology

Background:

  • Colonoscopy is a crucial endoscopic procedure for examining the colon.
  • Performing colonoscopies requires advanced skills in hand-eye coordination, visualization, and endoscope manipulation.
  • Increasing prevalence of colon diseases necessitates effective surgeon training.

Purpose of the Study:

  • To develop and describe a computer-assisted haptic simulator for colonoscopy training.
  • To provide a safe and realistic environment for surgeons to acquire and refine colonoscopy skills.

Main Methods:

  • Development of a haptic hardware interface utilizing a high-friction belt for force rendering and anti-slippage.
  • Implementation of a differential drive system with DC motors for translation and rotation control.
